Calvin Harris and Zayn Malik are busy hurling F-bombs at each other — over Taylor Swift

Random celebrity feud of the day: Calvin Harris has been forced to defend Taylor Swift's business choices after Zayn Malik appeared to take a jab at her on Twitter.

The trouble started when Malik retweeted an image, since deleted, that criticized Swift's choice to remove her music from Spotify as greedy. When Harris caught wind of it, his hand was forced — he had to defend the honor of his lady. Warning: The language in some of these tweets is explicit.
